Filter cartridges are designed be used with our filtration rigs, to capture and remove particulates and water from oils and diesel fuels. The cartridges remove and retain any water and dirt particulates present in your fluids for easy waste disposal and longevity of your machinery.
Fluid cleanliness, particularly in hydraulic systems, is extremely important and it is widely recognised that silt particles (<5 micron in size) are a primary cause of premature machine failure through abrasive wear of component surfaces. In addition water is a major cause of system damage through accelerated oxidation, corrosion and fluid breakdown.
Our filter cartridges are rated at 3 micron absolute and - based on multi pass - will attain high cleanliness levels. The cartridge will absorb all free and emulsified water. The media will gradually remove contamination particles down to less than ISO 16/14/11 or NAS class 5. This will extend the life of your oil or diesel fuel. We can supply filters for varying viscosities of oils, please contact us to help us identify your requirements.
High Visc/Cold Application (1888S)
These cartridges are designed to be used on high viscosity oils such as gear oils and for use on all oils and in very cold applications.
Filter Cartridge Maintenance
All of our filter rigs are fitted with a pressure gauge. This gauge is very important and directly related to the changing interval of your filter cartridge.
On start up of the rig the gauge indicates the running pressure of the rig. With new filter cartridges the pressure will rise until the new media is fully saturated then drop to a pressure of around 3-4 bar. Depending on the oils viscosity and temperature this will vary.
During filtration as the filter cartridges start to remove particles and any water present, the pressure gauge will slowly rise to around 7 bar. Eventually, the pressure will increase until the rig automatically shuts off due to the high pressure 'trip' that is built in or the fluid will create a bypass and the pressure will drop below its normal running pressure.
The filter cartridges give their optimum performance when 45% to 65% full of contaminants and under average contamination around 21/18/15 conditions should give hours of continuous use. If water is present this will significantly reduce the lifespan of the cartridges. Each filter media cartridge will absorb 1 litre of water each.
If there are 2 different systems to be filtered which contain different oil grades for e.g. 32cst swapping to a system 80cst, then the filter cartridges should be changed. If the filters if are fully depleted in their absorbing capacity, then simply slide the filter into the bag supplied with the new filter and save it until you go back on to a system that uses that grade oil.
